## Overview

This is a small student-and-teacher management app. Users navigate lists, search records, open detail views, and enter new student or teacher information; teacher additions update app-level state, while student additions remain local to the form. The React app also requests a message from an Express server, which connects to MongoDB and exposes a students endpoint. The README is empty, and some page and model implementations were not sampled, so uncertain wiring—especially the students API’s model access—is omitted.
